A source location privacy protection method based on dynamic phantom node strategy

Abstract

A source location privacy protection method for dynamic phantom node strategy, the method is aimed at source traceability attacks in wireless sensor networks, and the method is divided into the following steps: building a distributed network model, network initialization phase, determining the location area of ​​phantom nodes, phantom nodes The location area is divided, the phantom nodes are dynamically selected, and the backbone network is constructed. This method builds a distributed network structure oriented to privacy protection of source location, uses a dynamic phantom node strategy that considers the visible area, while controlling the length of phantom paths, the high randomness of phantom node locations is improved, and when constructing backbone routing Considering the remaining energy of the node and the number of neighbor nodes, the time required for the attacker to trace back to the source node is effectively prolonged. In addition, since the nodes on the transmission path always transmit data packets in the direction of the sink node, loop routing is avoided, and the energy consumption overhead and transmission delay are effectively controlled.

Description

technical field [0001] The invention relates to the field of wireless sensor network security, in particular to a source location privacy protection method for a dynamic phantom node strategy. Background technique [0002] The wireless sensor network (Wireless Sensor Network, WSN) has a very wide range of applications, involving medical, environmental, home, industry, aviation and military and so on. The wireless sensor network consists of a large number of low-cost micro-sensors deployed in the monitoring area. The energy supply, storage capacity, computing power and communication bandwidth of these sensor nodes are usually limited, so the function of a single node is relatively weak. The powerful functions of the node are realized through cooperation between nodes. In addition, the wireless sensor network uses an open and transparent wireless communication channel, which makes nodes vulnerable to malicious attacks by intruders when transmitting data. [0003] At present,...

Problems solved by technology

Although this method can enhance the protection strength of node location privacy, the data transmission path is too complicated, resulting in the transmission delay of data packets and the energy consumption of nodes. It is not suitable for networks with small network scale or short transmission path.
